Password Strength Checker

Estimate how guessable a password is, with pattern checks for repeats, sequences and common passwords. Typed text stays on your device.

About these password tools

The generator uses your browser's cryptographically secure random number generator, and the checker analyses text on your device. Neither sends what you type or generate to a server.

Strength results are estimates. The most important habits are using a different password on every site, keeping them in a password manager and turning on two-factor authentication.
